Interesting video.

 

He's done a lot of work with that engine since that video was released. Pretty wild stuff.

 

So,e mistakes were made along the way. At least with the mistakes out of the way, you now know how not to build a 12 rotor engine. I am almost more interested in the cool shop tools and 3d scanners, etc. It's been an interesting build so far though.

I hadn't watched any videos in a while... like years ago. I spend time on here now and my Roku box and youtube app spies on me and recommends his videos now so, I watch.
